Refactoring Legacy Apps to Microservices using AWS Migration Hub Refactor Spaces

This lab demonstrates the process of moving from a monolithic architecture to a microservice architecture.

Objectives

By the end of this lab, you will be able to do the following:

• Explore the monolithic application.
• Use AWS Migration Hub Refactor Spaces to create a refactor environment and define traffic routing.
• Leverage Microservices architecture.
• Use Amazon DynamoDB for storing and accessing shopping cart information.
• Use AWS Lambda as compute resource for accessing and manipulating the shopping cart.

Prerequisites

• Access to a computer with Microsoft Windows, Mac OS X, or Linux (Ubuntu, SuSE, or Red Hat)
• A modern internet browser such as Chrome or Firefox
• Be familiar with the AWS console
• Be familiar with AWS Migration Hub

Outline

Task 1 : Explore the Unishop legacy application.
Task 2 : Use AWS Migration Hub Refactor Spaces to create an environment that can replace functionality in the legacy application and route traffic to the replacement microservices (strangler pattern)
Task 3 : Build a new microservice to replace the shopping cart functionality using AWS Lambda and AWS DynamoDB
